Often reading disabled students in my learning strategies classes would move their lips as if reading out loud to themselves. This suggests they are over using the frontal lobe, and under utilizing the reading centres in the back of the left side of the brain. All of my students were identified through their IEP as Learning Disabled ~ Communication.
I suspect that most of them were dyslexic. I had great success improving their reading fluency using Orton-Gillingham based software.
When students with a specific reading disability (dyslexia) receive training in the foundation skills of reading, namely phonemic awareness, sound symbol association (phonics), decoding, vocabulary and comprehension new neural connections are made to the reading centres on the left side of the brain.
“One year following effective reading intervention, dyslexic children have developed left-side reading systems ( shown in black) in both the front and back of the brain.”
